Does the squeak correspond to the crank, or is it dependant on speed, whether cranking or not? I've known a few people who have had problems with coda hubs (BTW, that's called "semi radial" lacing), so that could be the problem. If spokes are loose (not likely), you would get play in all directions, and they would feel loose. Most likely, you need to tighten the "cones" a bit. The bearing cartriges could be worn, too, so maybe you should take the wheel to the shop this afternoon.
